upset: *** /sourceware/ftp/pub/cygwin/x86/setup.ini: warning - package libSuiteSparse-devel refers to nonexistent external-source: SuiteSparse
Marco,The problem was that libSuiteSparse-devel-3.7.1-1 was left without a source package of the same version. I moved that out of the way for now; let me know if you need it restored.
